The animation looks cool About the question...no ...gif have a very low quality, that is not visible if the image to save contain very few colors (no more than 255 : 255 may seems many but we are not talking of colors on a painter palette that could be mixed togheter,or diluited consider that the most simple gradient as from black to white contain dozens and dozens of colors. You may get better result by converting to index manually using a dedicated palette (=sampling the colors that you wish more to preserve ), playing with the settings (as the dithering options: dithering may help to emulate the missed colors but may also create a sort of chickenpox effect, another option should allow to minimize color bleeding when dithering, but at risk to enhance the chickenpox FX, no dithering avoid chickenpox but at the price of a posterize effect ..that may even be cool ) So there is not a fixed rule just several option to play with , according to the image with additional plugin you may also save animation as Flash(,swf) or as animated png (apng) that may have much better quality but also much bigger file size |

In a few words the xcf file and so the playback version is in RGBA mode, meaning that support several MILLIONS colors But gif support only index mode so that millions of colors are reduced to 255, and quality reduced on the same proportion |

"So is apng able to use millions of colors unlike gif?" Yes but the file may be much bigger More exactly apng support both Index (255 colors) and RGBA mode. so result and file size will depend by the image mode ( in gimp menu you may change from Image/image Mode... BUT here a warning, changing from RGB to INDEX is a destructive process, once done you may recover original quality only using UNDO ) |

That looks great.  APNG works nicely when only using a few frames.
